POV-Ray 3.5 beta4 for Windows, Win98, Athlon, 256MB.
The following crashes POV-Ray:
#declare X = .1;
#while(X <= 4)
sphere { <X, sin(X)^sin(X), -.1>, .02 pigment { rgb 1 } }
#declare X = X+.1;
#end
And yes, this *is* the shortest version I could come up. Calculating
once sin(X)^sin(X) doesn't seem to crash (even when sin(X) is negative).
Note that it also crashes if the sin(X)^sin(X) part is replaced with
F(X) and the F function is defined as:
#declare F = function(x) { sin(x)^sin(x) }

Same here. 3.5 beta 2 and 4, WinME, PIII.

This was supposed to have been fixed in beta 10, but it still crashes on
my machine.

Yes, not all of the change made its way into beta 10...

It further should be noted that the fix will simply issue an error for this
function if it encounters 0^0, which isn't defined. So the above won't work
anyway, but it of course will no longer crash in beta 11.
